Wider cockpit FOV slider, without changing external rendering, HUD or mirrors

[GunSlingerAUS]

As bigger displays become more affordable, flyers like me (55" screen) will want to see more of the cockpit. However, using the zoom slider to zoom backwards and increase the FOV makes external objects render at further distances, putting at me at a distinct disadvantage. If I use the right ctrl+right shift+numpad keys to move my pilots head, the HUD and mirrors become unusable (this is in the Tomcat).

 

I'd love to be able to see more of my cockpit without being disadvantaged, and without the glitches with the HUD and mirrors.

When you increase the FOV everything you see gets smaller. That’s just reality and can’t be changed. I always thought the default wide FOV limit in DCS looks rather fisheyed on a 16:9 screen and is maybe intended for triple screens and such. I have it limited to about 70% in order for it not to appear distorted. 
It would be great to have an FOV setting in the main GUI and not in the lua files. An axis assigned to zoom view can be adjusted or limited in the response screen but buttons assigned to this command cannot.
